The Twitter feed has a picture of Twain’s Huckleberry Finn. Rather, I think the paramark is a reference to the 2090th paragraph in the book (are there that many paragraphs in the book?). It may be a Vigenere cypher.

Y’know, good call. I saw that cover… and I didn’t even make the connection of it relating to a paragraph in the book. I’ll bet you’re on to something there, CRSP.

I have the book on my iPhone (Classics App)… any suggestions?

If it is a Vigenere cypher, we’ll need a passphrase to plug in here:

Ugh. I’ll be damed if I’m going to count 2,090 paragraphs. That can’t be it. I mean it could be, if someone was cruel. So it probably is.

My hunch:

The paragraph will be a one word paragraph. Like a word a character says. And that word won’t have any repeating letters in it.

Anyone have the book in a digital format (The Gutenberg Project?). And a way to thumb through or have a word processor automatically bring you to a paragraph (or word) count?

What worries me is all the numbers and letters combined in the code.

[Here’s the same edition](http://www.archive.org/details/adventureshuckle00twaiiala) of Huck Finn the cover appears to be from. Not sure how to get it in a format where you can flip to a paragraph though.

> If it is a Vigenere cypher, we’ll need a passphrase to plug in here:

The problem is that it doesn’t appear to be a typical Vigenere, with the inclusion of all those numerals. Normally, a Vigenere wraps around the alphabet, although it is not impossible to come up with various encodings that would map numbers to letters. Most, if not all, of your online solvers will ignore any numerals in your cipher text.

Vigeneres are actually pretty easy to solve, even if you don’t know the passphrase. There’s two different common attacks for it, one involving index of coincidence and another involving finding repeating digraphs or trigraphs and their spacing to figure out the keyword’s length. After that, it’s a matter of solving several simple Caesar (shift) ciphers based on frequency analysis. Way back when, I wrote a simple BASIC program to prove to myself how simple it is to solve. Problem here is, for this analysis, is that I don’t know how the letters and numbers are meant to map. With a traditional Vigenere, it’s just a simple shift. Also, if the keyword is of any reasonable length (say, more than five characters), we’re going to have a difficult time using this approach as the ciphertext may not yield enough letters for a frequency analysis.
